Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750180, here are decompositions:

3 + 8750177 = 8750180
73 + 8750107 = 8750180
79 + 8750101 = 8750180
163 + 8750017 = 8750180
199 + 8749981 = 8750180
277 + 8749903 = 8750180
367 + 8749813 = 8750180
409 + 8749771 = 8750180

Showing the first eight; more decompositions exist.
